MultiTone Generator
Tutorial
This is a tutorial of the MultiTone Generator App. The MultiTone Generator provides means to create and play up to 16 completely individual tone combinations in parallel. If there are any questions, please just send an Email to tom@ee-toolkit.com
This is the main interface of the MultiTone Generator App. Click on the expand button to expand the tone section. Add or remove tones. Tone numbers are shown on the left side. Additional menu options (Play All, Play Sequence, Remote Play) are available and will be explained further down in this tutorial.
Enter a frequency in the text field (PRO version range: 1Hz – 21kHz, Free version range: 100Hz – 10kHz). Select one of the four waveforms: sine, rectangular, triangular or sawtooth. Press the play button to start or stop playback, individually for each tone. The frequency slider provides an alternative to the text field entry via the keyboard. Set the volume via the volume slider per tone. The master volume can be set via the slider on the bottom or the vol+/vol- buttons on your iPhone or iPad.
In sweep mode, the generator runs in both directions, min => max frequency and max => min frequency within the specified time.
If the Repeat button is selected, the sweep will repeat in a loop. If you enable the Siren Mode (Setting menu), the sweep function increments from min to max and then decrements to min again. Then it repeats from min to max and so on.
Select a start frequency by entering a value in the text field or set the frequency via the frequency slider. Then tap on “Set Start”. This sets the sweep start frequency. Do the same for a stop frequency.
The sweep time can be set via the sweep time slider. Its max value can be configured in the Settings menu.
The current sweep time is indicated by the sweep timer.
Each tone can be fine tuned using the Fine-Tune menu.
Using the Play All menu, it is possible to play all tones at once, or play specific tone sets at once.
With the sequence play menu it is possible to create fully custom tone combinations and play them sequentially. It is also possible to save a sets of sequences like a playlist and load it at any later point in time. Play/Pause, Stop, Previous and Next playback commands are of course supported as well. In addition, also Repeat All and Repeat Once is available.
The Remote Play menu provides a powerful overview of all tones and means to tune the volume of each of them at custom granularity. A reference tone can be set if needed. Playback as sequence is supported as well.
The sidebar menu provides shortcuts to several menu options.
The MultiTone generator supports a menu for saving and loading complete tone configurations on the main interface. This is particularly useful when working on and experimenting with different sets of tone groups.
The settings page of the MultiTone generator provides additional means for individual configuration.
The min/max range of the frequency sliders can be customised here. Also the max sweep time can be entered.
The MultiTone generator has English or German language support.
The frequency slider can be set for linear or logarithmic mode.
Background modes are set automatically based on the iOS global setting: Dark or Light.
The LP filter is used to enable/disable a Low-Pass Filter on the output signal. This applies to non-sine wave signals like square, sawtooth and triangular waveforms. Enabling the filter avoids certain modulation effects, which can occur when playing audio signals that are comprised of higher frequency components (outside the cut-off frequency of your iPhone’s or iPad’s audio output). This is not relevant for pure sine signals, but of course for square, sawtooth and triangular signals it is a quite useful setting.
The MultiTone Generator works with Audiobus and Audiobus Remote! Seamlessly integrated with Audiobus and Audiobus Remote, it empowers you to create, mix, and control your sound with unparalleled flexibility – perfect for musicians, sound designers, and audio enthusiasts alike!
